Aspirin May Be Adequate for Venous Thromboembolic Event Prophylaxis after Revision Hip and Knee Arthroplasty

Abstract

Introduction: The optimal prophylaxis for prevention of venous thromboembolic events (VTE) after total hip arthroplasty (THA) and total knee arthroplasty (TKA) remains unknown.(1) Current studies focus on primary arthroplasty and there are little to no data on the ideal prophylaxis for VTE following revision arthroplasty.(2) Revision surgery, due to its complexity, longer operative time, higher risk of bleeding and infection diff­ers from primary arthroplasty.(3) The objective of this study was to evaluate whether aspirin, known to be e­ffective for prevention of VTE after primary arthroplasty, is also e­ffective against such events following revision THA and TKA
